The 89HT0808PYDABG8 interface module produced by Advantech Industrial Automation Group is a special-purpose application module that performs data communication in an industrial environment. It is an important part of the industrial communication system and plays the role of data transportation

Application Field

The 89HT0808PYDABG8 interface module is widely used in applications where communication between industrial automation devices and computers is needed. It can be used in applications such as process control, automation equipment, and long-distance communication systems. It can also be used in applications requiring efficient data exchange between different network protocols, such as special-purpose PLCs and PC-based control units.

Working Principle

The 89HT0808PYDABG8 interface module utilizes the type 8095 communication protocol. This protocol is designed to scale the number of bytes transmitted in a single transaction for increased efficiency and performance. The protocol operates with an asynchronous format where each data item is preceded with a flag and a start bit. After being parsed by the protocol, the appropriate data is transmitted through the module. The device also supports parity, time-stamping and use of multiple transmission formats as needed.The 89HT0808PYDABG8 interface module includes a host port and a broadcast port. The host port allows data to be exchanged between two devices, while the broadcast port is used to transmit data to multiple devices simultaneously over the same physical medium. When using the broadcast port, the data can be forwarded to many industrial devices such as PLCs, DCSs, and embedded control systems.
